Agriculturalism, also known as the School of Agrarianism, the School of Agronomists, the School of Tillers, and in Chinese as the Nongjia (農家/农家), was an early agrarian Chinese philosophy that advocated peasant utopian communalism and egalitarianism. The Agriculturalists believed that Chinese society should be modeled around that of the early sage king Shen Nong, a folk hero which was portrayed in Chinese literature as "working in the fields, along with everyone else, and consulting with everyone else when any decision had to be reached." They encouraged farming and agriculture and taught farming and cultivation techniques, as they believed that agricultural development was the key to a stable and prosperous society. Agriculturalism has significantly influenced Chinese thought, and has been viewed as an essence of the Chinese identity.

Agriculturalism dates back to the Spring and Autumn and Warring States era, during a period known as the "Hundred Schools of Thought". Throughout this period, competing states, seeking to war with one another and unite China as a single country, patronized philosophers, scholars, and teachers. The competition by scholars for the attention of rulers led to the development of different schools of thought, and the emphasis on recording teachings into books encouraged their spread. The result was an era characterized by significant intellectual and cultural developments. The major philosophies of China, Confucianism, Mohism, Legalism, and Taoism, all originated from this period.
